Be itknown thatI; HARRIS F.

ous "devices and machines needing power must be located at relatively remote points. For instance, it may be desirable to, have power to drive the dairy 'machinery. It is also necessary to have some kind of power to pump water. Very oftenapump is located at a different point froin'fithe dairy. Or for that matter, the ownerfmay desire to have his internal combustion. engine in the cellar, where it will not freeze in winter. He may wish to transmit power to his dairy machinery or to his] pump and this, of course, .willbeoutside of the cellar.

It is found that ordinary belting is very unsuitable for thispurpose and is alsodantected position. It is the object of "this invention to provide a very simple power transmission line equipped with the devices necessary to make it a practical success.

Figure 1 is a view in general outline of the transmission line showing it coupled up with a pump and a gas engine motor.

f Fig. 8* is aside elevation of thespacer used to space the cables.

M designates the motor, which may be an electric motor or an internal combustion engine. This can be used in the engine house, dairy or other place to drive other machinery, suchas shafting a, for example.

This motor drives a connecting rod 6, which rocks the rock arm 0, which is part of the double bell crank rocker and is supported the squared end of which is fastened the rock arm 9. Through the ends of the rock arm 9 are threaded thehook bolts h, upon Which hooks the clevis iof a cable tightener This comprises simply a spool journaled in the ends ofthe clevis. These reels are supportedon small shafts j that run "through the ends of the clevis and terminate in squared ends Z which are suitable for the application of a wrench to turn the spool to A These cables (preferably wire) are in tended for relatively long distances of 50,

100 feet, or more, and itis advisable to have gerous passing near the ground in anunprointermediate supporting posts 01. on which are supported rotatably the grooved rolls 0 over which the cable may be run as a support. These cables would objectionably lash back and forth and vibrate up and down were it not for the spacing frames that I provide between the supports. This not only prevents the lower cable from drawing away from the upper cable but also prevents it from approaching the upper cable. These spacers are designated p in Fig. 1, and are detailed in Fig. 8, which is a view looking edgewise at the spacer. It will be found that it comprises two vertical pieces of strap iron connected at the top by a flat piece of strap iron which is secured to the two vertical runs of strap iron by the hook bolts 9 which also pinch the cable 7" tightlyl to the top of the spacing frame. On the lower end of the spacer hook bolts 8 support a tube 75 through which the cable it runs freely. Hence the upper cable is rigidly fastened to the spacer and the lower cable runs through the tubing in the spacer, which serves to accurately keep the oppositely traveling cables in properly spaced relation. The amount of spacing can be adjusted by moving the bolts 3 along to other holes 5 in the upright straps.

On the work end of the line is a three-arm bell crank lever, two of which are the power arms and the other the resistance arm. The power arms are in alinement and have hook bolts '22, one bolt passing through each arm to hook into a clevis m, which rotatably supports the pulley y around which the cable is run and then clamped togetherby the clamp z. This enables a certain turning movement to take place due to the action of the bell crank arm without wearing the cables, for

the cable merely turns with the pulley as the pulley accommodates itself to the bell crank arm swinging through its arc.

I united by suitable coupling so as to stand a side draft, for the bearing cannot perhaps be so placed as to be exactly perpendicular to the line of draft.

WVhat I claim is:

1. A mechanical power transmission, having in combination, a pair of rock arms supported to rock at points remote from each other, cables connecting the ends of one rock arm with the ends of the other rock arm, and a spacing frame comprising a member rigidly connected with one cable and having a tubular member that ensheathes the other cable and allows the cable to slide therethrough.

2. A mechanical vpower transmission, comprising a pair of rock arms supported to rock at points remote from each other, cables connecting the ends of one rock arm with the ends of the other rock arm, and tightening devices for taking up slack in the cables, comprising spools about which the cables wind and a ratchet and pawl.

3. A power transmission, having in combination, a pair of rock arms supported to rock at points remote from each other, cables connecting the ends of one rock arm with the ends of the other rock arm, and a spacing frame comprising a rectangular frame having one of the upper or lower cross members adapted to move with the cable that it is secured to and the other member arranged to slide on the cable which it engages.

4:. A mechanical power transmission, having a pair of rock arms supported to rock at points remote from each other, cables connecting the ends of one rock arm and the ends of the other rock arm, and a spacing frame comprising a rectangular frame having upper and lower cross members and two uprights, the uprights being perforated and one of the cross members adapted to be bolted at various points along the slots and one of the said cross members being attached to one cable to travel with it and the other cross member being attached to the other cable to slide upon it.

In witness whereof I have hereunto set my hand on the 5th day of March, 1919.
